ninja won't start up

[ptg122]

i tried to open ninja trader and got this error: Unhandled exception: value cannot be null. and then it stopped loading. i tried it several times with the same problem.
i went to the ninja forum and found someone with a similar problem and he was advised the remove and reload ninja trader. i did this and now when i try to start ninja
nothing loads at all. i remove it again and reloaded it and had and am still having the same problem. for a few seconds the blue circle comes on but then nothing. how
do i fix this?
